New brane-like solutions in modified four-dimensional Einstein-Gauss-Bonnet gravity
D. Bazeia, R. Menezes, A. Yu. Petrov +1
We investigate solutions of a new Einstein-Gauss-Bonnet gravity ( ). We first describe the bulk vacuum solution, then we add a massive probe scalar field, and we foll…

Analytical solutions for Maxwell-scalar system on radially symmetric spacetimes
I. Andrade, D. Bazeia, M. A. Marques +2
We investigate Maxwell-scalar models on radially symmetric spacetimes in which the gauge and scalar fields are coupled via the electric permittivity. We find the conditions that al…

Two-field models in the presence of impurities
D. Bazeia, M. A. Liao, M. A. Marques
This work deals with systems of two real scalar fields coupled to impurity functions, meant to model inhomogeneities often encountered in real physical applications. We investigate…
